Manchester United have been told to forget about signing Bologna striker Marko Arnautovic.

The Austrian international has emerged as a surprise target for the Old Trafford club.

However, Bologna sporting director Marco De Vaio has shut down the move.

De Vaio told Italia1: "It's not a question of money, he's priceless for what he means to us.

"We want to move forward with him because we are convinced that he can get better and help us grow. He is always the first in training to push the others, he has no market value."

The comments come after Arnautovic's brother and agent, Danijel, confirmed the potential transfer.

"It's true that there is an offer from a well-known club," Danijel Arnautovic told Austrian outlet Kurier.

"I'm in contact with Bologna to see if that [offer] can be realised."
